In general, the extracellular material of each type of cartilage is firm but pliable. Cartilage consists of a dense network of collagen fibers (the type dependent on the subtype of cartilage) and sometimes elastic fibers, each embedded in chondroitin sulfate (a jelly‐like substance). The collagen fibers add great strength to cartilage, while the ability of cartilage to assume its original shape after deformation is due to the chondroitin sulfate. The three primary types of cartilage, namely hyaline (articular) cartilage, fibrocartilage, and elastic cartilage, can be distinguished from each other by the type of fibers within the matrix.
